And Abram went up out of Egypt, he and his wife, and all that he had, and Lot with him, into the wilderness. Abram had become very wealthy in livestock and in silver and gold. And he went to the place whence he came, into the wilderness as far as Bethel, as far as the place where his tent was before, between Bethel and Ai, to the place of the altar, which he built there at first, and Abram there called on the name of the Lord.
And Lot who went out with Abram had sheep, and oxen, and tents. But the land could not support them while they stayed together, for their possessions were so great that they were not able to stay together. And there was a strife between the herdsmen of Abram’s cattle, and the herdsmen of Lot’s cattle, and the Canaanites and Perizzites then inhabited the land. And Abram said to Lot, “Let there not be a strife between me and thee, and between my herdsmen and thy herdsmen, for we are brethren. Lo! is not the whole land before thee? Separate thyself from me; if thou goest to the left, I will go to the right, and if thou goest to the right, I will go to the left.” And Lot having lifted up his eyes, observed all the country round about Jordan, that it was all watered, before God overthrew Sodom and Gomorrha, as the garden of the Lord, and as the land of Egypt, until thou come to Zoar. So Lot chose for himself the whole plain of the Jordan and set out toward the east. The two men parted company: Abram lived in the land of Canaan, while Lot lived among the cities of the plain and pitched his tents near Sodom. But the men of Sodom were evil, and exceedingly sinful before God. And God said to Abram after Lot was separated from him, Look up with thine eyes, and behold from the place where thou now art northward and southward, and eastward and seaward; for all the land which thou seest, I will give it to thee and to thy seed forever.
And I will make thy seed like the dust of the earth; if any one is able to number the dust of the earth, then shall thy seed be numbered. Arise and traverse the land, both in the length of it and in the breadth; for to thee will I give it, and to thy seed forever. And Abram having removed his tent, came and dwelt by the oak of Mamre, which was in Hebron, and there he built an altar to the Lord.
